Elicenser unable to work with old products and new ones?

I am using Groove Agent 3, Virtual Guitarist 2 and Virtual Bassist that all work with a USB elicenser. If I try to install some new products, I get a notice that elicenser software must be updated. If I update it, those three products don’t validate any longer until I install a previous older version. It seems I can’t get both old products and new ones to work with the same version of elicenser software. I am using Mac OS X 10.13.6. I operate the 32 bit plugins using 32 Lives.
